Resolution, I use 75dpi for my final images, however when I first
scan them in it depends on what changes I'm going to make.
If I need to make the image or any part of it larger then a higher
resolution is desirable.
Compression is usually part of any decent image manipulation software
you can usually control the amount of compression used on a .jpg
but more compression=less quality........
.gif's are quite a bit larger then .jpg's but support features like
transparency that a jpg does not but you can usually reduce the size of
a
gif by reducing the amount of colors in the palette.
Normally I'll keep a TIFF and an UFO (which is my programs
proprietary file format for saving objects) for editing and convert it
to whatever
afterwards. .jpg's loose a little quality every time they are opened
for editing.
I try to keep all my pages under 40k.............so if that serves as a
point of
reference...............
Hope this helps............
